That's the equivalent of a credit card.
A new study has suggested that the average person globally could be eating an average of 5 grams of plastic every week, the equivalent of a credit card.
"Since 2000, the world has produced as much plastic as all the preceding years combined, a third of which is leaked into nature," the report read.
However, water is not the only source of the plastic ingestion, with beer and salt also found to contain tiny traces, while shellfish are another major source, as they consume the plastic, and they are then in turn consumed whole.
Marco Lambertini, director general of WWF International, spoke of the fact that, on average, people are ingesting 250 grams (approximately nine ounces) of plastic each and every year:
"Not only are plastics polluting our oceans and waterways and killing marine life, it's in all of us. If we don't want it in our bodies, we need to stop the millions of tons of plastic that continue leaking into nature every year."
So is consuming that much plastic a bad thing?
According to Professor Alastair Grant, of the University of East Anglia, there isn't much evidence on the subject: ''I don’t think there’s evidence that eating plastic particles at these sort of levels is a significant health risk.''
Bad or not, the idea chowing down on plastic isn't a particularly pleasant one.
